Thermal Insulation
Frequently asked questions (FAQ)
The thermal conductivity is decisive for the thermal insulation properties of an insulation material. The thermal insulation property indicates which thermal energy (W) flows through a component per meter (m) at a temperature difference of 1 Kelvin. The unit of measurement is W/mK and is abbreviated as small lambda (?). The basic rule is that the smaller this value, the better the thermal insulation property of the insulating material. Examples: PUR foam 0.037 / polyester fibre mats Vibra?fibre 0.037 / melamine foam Basotect? 0.033
Structure-borne sound insulation - anti-drumming, the transmission of sound in solid bodies. While the construction materials of machines and buildings such as cast iron, steel and concrete are good conductors of sound and are therefore described as sound-reflecting in analogy to the material consistency, rubber, on the other hand, conducts sound poorly and is very well suited as a softer material for structure-borne sound insulation. The damping effect for structure-borne sound waves is due to their partial reflection at the interface of the materials and only a part of them penetrates the intermediate layer.
